Product Description

*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***

** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 3 Options Are Now Available ***

Option 1: 

Buy strengthened brass gears + hi-torque motors in quantity of 1 set for 1 mirror or 2  sets for both mirrors ($49.99 / $89.99). Requires 24 hour epoxy of brass gear onto main shaft in your unit.  You will re-use your existing main shaft and epoxy on a new brass gear section.


Option 2:

Buy strengthened brass gears pre-mounted to a new machined steel main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  Does not require any epoxy cure time to install, its plug and play.


Option 3:

Buy a rebuilt complete motor drive unit with new hi-torque motor and brass gear pre-installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened BRASS spur gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened spur gear made from solid gear BRASS with a thicker cross section to eliminate the stress concentrations which cause fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can buy the gear/motor combo for one of both sides, and with the spur gear pre-attached to a new main shaft, or loose. Loose gear orders require installation of the spur gear onto the main shaft using 24 hour epoxy - please refer to the DIY article link above.  We have thoroughly tested our redesigned spur gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.

    You don't need to buy a new mirror. These parts are the fix/upgrade you need.

  3. great parts 5 Star Review

    Posted by on 18th Apr 2021

    I read about this product on line, I liked the fact that the gears are brass, I bought a set for my daughter’s 08 GMC Acadia and the they fit and worked perfectly, then I bought a set for my friend’s 09 Tahoe, unfortunately I bought the gears and motor only, the reason I say unfortunately is because I should’ve bought the assembly gear set, again my fault, because if you don’t you have to epoxy the gear to the worm gear yourself which takes about 24 hours to dry not to mention a trip to the hardware store to get the epoxy and the cost, in the meantime you’re driving around without your mirror and wires hanging summarize...get the assembly with both gears, it’s a little more money but you’ll save a lot of time and aggravation, and if you’re not too mechanical savvy and don’t have the right tools I would strongly suggest buying the motor assembly, yes it’s about $100 more but then you’d be able to do it easily, just make sure you order the right one... left side or right side, after saying all this I put mine together works like a charm... twice as fast as the old one...a little noisier but that’s understandable having metal gears
    All in all it’s a great product and I don’t think I’ll ever have to replace them again...they’re made to last!

  6. Money savings DIY fix 5 Star Review

    Posted by on 8th Apr 2021

    After buying parts I kind of set away and kept putting off the repair thinking it was gonna be in depth repair. After doing the drivers mirror in maybe 2 hours and realizing it wasn't that bad I did passenger mirror in like 45 minutes. I will suggest to spend the extra $10 and buy the gear already mounted to spindle I did premount and the single gear I had to glue. Easy to glue it but their is a 24 hour waiting time before reinstalling the gear assembly back into the gear box. With preinstalled it's disassemble swap and reassemble. Can't say how happy that I did this and both mirrors work great and saved me a fortune and needless to say buying the new mirrors from dealer is expensive and will break just like first ones

  7. Folding Mirror Motor 5 Star Review

    Posted by on 7th Apr 2021

    I replaced my folding mirror motor with a new gruven motor and it worked great, you can tell the motor is strengthened because my passenger mirror folds in a little faster than my drivers side and my drivers side mirror is new factory mirror

    My parts were well done, the instructions were clear and concise, and Paul from Gruvenparts was responsive and pleasant. The mechanism went on as the video detailed and works like a charm.well done!

  9. excellent choice 5 Star Review

    Posted by on 28th Mar 2021

    My mirrors stopped folding and became bouncy on my 09 Silverado. I was referred here by a forum member. At first i was ify. But ordered anyway. Maaannnn am i glad the worm gear is soild. And altho the gm motor has a brass gear (atleast mine did) these new ones definitely live up to the term high torque. And the instructions omg could not of been any easier. Loved the extra tips. Kinda wish i was told i had to go online to get them but none the less great write up and great gear/motors.

  10. Very satisfied customer 5 Star Review

    Posted by on 27th Mar 2021

    2007 GMC Took me awhile to get to swopping new motor with the old ( below freezing for extended periods ). I followed the installation video and had no problems - the video was easy to follow and poined out any possible problems you might run across. Took me about an hour and a half cause I'm very cautious. New motor is way better than the old one - in every way.
